Newton's Second Law (Law of Resultant Force )

The Hooke's law is given by:
F = -kx

Where we have:
F: restoring force
k: spring constant
x: distance the spring has been stretched or compressed from the equilibrium position

Since the force can be expressed as:

we can rewrite the Hook's law as:

furthermore we have:

, where

thus
